Some gas molecules move at speeds of 542 meters per second. How fast is this in miles per hour? 542 =? 1h Solve by dimensional a
artcher [175]

Answer:

1212.42\ \text{mph}

Explanation:

We need to convert 542\ \text{m/s} to \text{miles/hour}

1\ \text{mile}=5280\ \text{ft}

1\ \text{ft}=12\ \text{inches}

5280\ \text{ft}=5280\times 12=63360\ \text{inches}

1\ \text{inch}=2.54\ \text{cm}=0.0254\ \text{m}

63360\ \text{inches}=63360\times 0.0254=1609.344\ \text{m}

So

1\ \text{mile}=1609.344\ \text{m}\\\Rightarrow 1\ \text{m}=\dfrac{1}{1609.34}\ \text{miles}

1\ \text{hour}=60\times 60\ \text{seconds}\\\Rightarrow 1\ \text{s}=\dfrac{1}{3600}\ \text{hour}

542\ \text{m/s}=\dfrac{\dfrac{542}{1609.34}}{\dfrac{1}{3600}}=1212.42\ \text{mph}

The speed of the gas molecules is 1212.42\ \text{mph}.
